Hello
I would like an info
following the guide from here:https://github.com/lewei50/Solar-PV-Monitoring/blob/master/HomeAssistant-InfluxDB-Grafana/README.md
I have implemented iammeter with grafana in home assisatant
according to the wiring diagram there are 3 pliers (ct) but in the packages solariammeter.yaml are used only used
a = ct1
b = ct2
I would like to understand
2 = ct3
because it is not mentioned in the calculation
my iammeter is 380t
thank you

Thank you for the explanation.
I understand how it works.
sorry if I drive you crazy.
You are very kind and very good at explanations

ct3 is not used because all data has been calculated by ct1 and ct2

Hi,

The WEM3080T(three phase energy meter) supports split-phase  usage,

You can consider it as three single-phase energy meters.
When you use it to monitor the solar PV system that both inverter and grid are single-phase, you just need to use two phases of the three.
One phase is used to monitor the grid export/import, one phase is used to monitor the inverter output.

Then all other parameters will result from the calculation of these two phase .

How to calculate the other parameters ,please refer to 

https://community.home-assistant.io/t/monitor-your-solar-pv-system-in-home-assistant-energy-dashboard-vs-energy-management/342710#get-the-five-key-parameters-of-solar-pv-system-by-ha

Although it is an article about the monitor the solar PV in home assistant, parameter calculation section is based on a universal formula.

hi I realized today that he no longer gives me the data in percentage and home assistant from this error

ERROR (MainThread) [homeassistant.helpers.template_entity] TemplateError('ZeroDivisionError: float division by zero') while processing template 'Template("{{ states('sensor.selfuse_energy_monthly')|float / states('sensor.yield_energy_monthly')|float }}")' for attribute '_attr_native_value' in entity 'sensor.self_consumption_rate_monthly'

help please

You can add a judgment of sensor.yield_energy_monthly>0 to value_template
